Horizon Alert
Summary of the vulnerability and why it matters
NETGEAR DGN2200 devices contain a vulnerability in the dnslookup.cgi script. This flaw allows authenticated users to run unauthorized commands on the device's operating system. The potential impact includes the compromise of device control and the execution of malicious code.
- Vulnerable: NETGEAR DGN2200 devices
- Flaw: OS command injection
- Impact: Unauthorized command execution
Attack Path
How an attacker could exploit the issue
This vulnerability allows an attacker to execute arbitrary operating system commands on a targeted device. The attack requires the attacker to be authenticated to the device. Once authenticated, the attacker can send a specially crafted HTTP POST request to the dnslookup.cgi script. This request contains shell metacharacters within the host_name field, which are then interpreted by the system, leading to the execution of the attacker's commands. The impact of this attack could include unauthorized access and modification of the device's configuration or data.
- Authenticated access to the device is required.
- Attacker sends a POST request.
- Arbitrary OS commands are executed.
